Benefits of technology
"The present invention relates to an x-ray apparatus for scanning an object that reduces the radiation dose for the object during the scanning process. This is achieved by using a diaphragm support system that includes at least two individual diaphragms that can be controlled as a function of the radiation intensity and the size of the object being irradiated. The diaphragms can have different radiation permeability, and can be made of different materials and thicknesses. The overall intensity of the x-rays acting on the object can be adjusted by selecting the appropriate individual diaphragm settings. The image processing system can also control the x-ray apparatus based on the image information provided by the x-ray detector, allowing for a more targeted approach to the object being scanned. The technical effects of this invention include reducing the radiation dose for the patient, improving image quality, and reducing the time required for the scanning process."
Problems solved by technology
The patient is exposed to ionizing and potentially harmful radiation.
High exposure doses may lead to radiation injury after longer treatments or interventions, for example, in the head region and in the brain.
The radiation injury may result in reddening of the skin or cause tissue damage.
The radiation dose cannot be reduced arbitrarily, since the image quality which is essential to the examinations suffers as a result.

Embodiment Construction
[0026]FIG. 1 shows an x-ray apparatus 10 as an example of an x-ray diagnosis device 12. The x-ray diagnosis device 12 scans an object, for example, a patient 14. The patient may be lying on his / her back on a patient support 16. The x-ray apparatus 10 may include an x-ray source 18, which is positioned above the head of the patient 14, and an x-ray detector 20, which is positioned below the support 16. The x-ray detector 20 supplies image information 22 to a central control unit 24. The central control unit 24 supplies a control signal 26 to an x-ray generator 28, which controls the x-ray source 18. An adjustable diaphragm system 32 is arranged below the x-ray source 18 and in the radiation path 30. The diaphragm support system 32 may include a disk-like x-ray diaphragm 34. Several individual diaphragms may be provided in a disk-like and rotatably mounted diaphragm support 36. By selecting a suitable individual diaphragm in the diaphragm support 36 using a control signal 38 from the ...

A diaphragm system for an x-ray apparatus for scanning an object is provided. The diaphragm system includes a diaphragm support arranged within a radiation path of an x-ray beam. The diaphragm support includes at least two different individual diaphragms. The at least two different individual diaphragms may be controlled as a function of a definable radiation intensity and / or the size of a surface of the object to be irradiated and can be introduced into the radiation path.
Description
[0001]This application claims the benefit of DE 10 2007 019 334.5 filed Apr. 24, 2007, which is hereby incorporated by reference.BACKGROUND[0002]The present embodiments relate to a diaphragm for an x-ray apparatus.[0003]A patient may be continuously x-rayed during a medical treatment and / or medical intervention, such as an endoscopic intervention. The patient is exposed to ionizing and potentially harmful radiation. High exposure doses may lead to radiation injury after longer treatments or interventions, for example, in the head region and in the brain. The radiation injury may result in reddening of the skin or cause tissue damage. A treating physician and the medical support personnel are also exposed to continuous scattered radiation during the treatment, since they are close to the patient during the endoscopic intervention. Accordingly, a reduction to the exposure dose for each party is desired[0004]The strategies used to prevent unnecessarily high exposure allow for a partial...
